Compression - Show Off Your Compressor

[kams1973]

Well my pin up girl is a 1957 (the year I got my first job working in a garage) Brunner. I purchased it off a truck that came through with several compressor he had for sale in 1976 when all the gas stations started closing and going to self service. It has served me over 35 years every day. If you can find one of those old compressors, they are much better than any thing you will find for $1000. I also have 2 Quincey compressor that were made sometimes in the 60's. Still pumping air.

That old Brunner is awesome. I have an old Brunner pump I've partially rebuilt, and it's a tank.

For my 120 gallon horizontal I ended up getting some isolator pads from McMaster Carr...

They work well and also have enough length to allow leveling the compressor.

Heavy Duty Vibration-Damping Leveling Mounts They are about $7 each.

Hello... was looking for some help on this "monster" compressor
Gardner Denver model APNFRA it has 7 -7/8 " bores and 4 -1/2 " stroke.
i calculate approx 440 ci. it came with a 20 or 25 hp 575v motor 3ph.
at 885 rpm this unit tated at 60 psi
im wondering how much cfm it would be... note the 2 1/2 " dia down pipe into the tank.
im going to try to run it with 2 x 5hp (7.5 actual) robbins meyers 213 frame motors at i estimate 450 rpm or so ( small pulleys)
not sure if gonna work or not hoping to trade cfm for pressure...lol

During my current compressor rebuild I found a couple websites that have RPM calculators that helped me find the correct dia. drive pulley to allow me to swap a 7.5 hp 3-phase motor with a 5 hp single phase. In my case I am looking at a 30% reduction in power so I did some fancy math using the online calculators to determine the correct drive pulley diameter. Hope they help.

Here is a page from a PDF I got on the Quincy website... Lots of useful formulas...

 

[Gratefuldiver]

You can find the specs here:
http://www.mason-industries.com/masonind/_doc/pdf/ND26.pdf

It is obviously important that you pick mounts for which your compressor is not too heavy. But it is equally as important that you get ones for which your compressor is not _too light_. If you don't have enough weight, there will not be enough force on the mounts to actually deflect them.

My compressor weighs about 650 lbs., so I picked ND-B-Red. Their range is 110 - 235 lbs each, which puts it at 440 - 940 with 4 of them. At 650 lbs I am right in the sweet spot, and the ND-B series had the right physical dimensions to fit my compressor legs perfectly.



The Mason vibrations isolators are sweet. When my compressor starts up you can actually see it deflect slightly as the motor's torque overcomes its static inertia. When it's running you cannot feel a single vibration in the floor. I can actually grab the compressor and wiggle it slightly, but it immediately returns to its natural position. My compressor is bolted to the mounts, but it is not bolted to the floor. The mounts are completely rubber-covered, even on the bottom, so they grip my epoxy-coated floor well enough just with friction.

I like how they fit inside the legs of my compressor, but that can also be mounted under a flat-bottom leg if that is what your compressor has. You can even mount them upside-down.

I got a set on Amazon for $18 each. Waiting on 3 as they are back ordered

 

[Tim The Tool Man]

I added some Mason vibration isolators:

...but they are not needed so much, the compressor is so smooth...

Old tire tread found on the side of the road (road alligators), though not as pretty, works just as well. Used it on my last compressor for years...

Another good source is Zoro (that's where I got mine). It's not the easiest website to navigate, but there are always discount codes out there for Zoro.

 

[Gratefuldiver]

They have them in stock and $5 cheaper so I canceled with Amazon and ordered from Zoro. Found $5 off online. Thanks

I also got my single phase motor yesterday and funny enough sold my 3 phase on ebay at the same time

I was gifted a Binks Lo Boy without an motor. Was told the pump works just fine. I would like to put a gas engine on it. Anyone have some ideas on what I would look for?

What model number is it?
Was it originally meant for an electric motor?
If so, find out what the max rpm is on the specifications, if possible.
Maybe there's a tag on it?
Electric motor will turn 1750, then of course there's pulley ratios to the pump.
Gas engine will normallly be run at 3400-3600rpm.
So be careful that you don't spin it too fast.

The volumetric efficiency of a single-stage compressor is about 50% - 60% depending on size and speed. That would make your unit's output somewhere around .125 cubic feet per revolution at 50% efficiency.

The power required to compress air is a fairly simple calculation and from that you can calculate the correct compressor speed. Once you have a rough speed calculated, run the machine with the intended motors and check the motor current. Using an adjustable sheave on your motors you can adjust and balance the motor power.

Make sure you're spinning it fast enough. Some compressors have minimum operating speeds to ensure adequate lubrication.

So I am finally ready to show off my rebuilt circa 1978 American Kellogg 340TV compressor!

---Sorry this post is picture heavy but I can't figure out how to do thumbnails.

I started rebuilding this compressor about 18 to 24 months ago starting and stopping several times along the way. It is through this rebuild that I initially found this site three years ago while researching American Kellogg air compressors.

I found and bought the compressor through Craigslist for $250.00. It was in rough shape, dirty and covered with this sticky, gummy, thick white sludge. I was told that the valves leaked and it had a 3-phase 7.5 hp motor on it.

First I really scrapped and scrubbed down the entire compressor. Then I completely dismantled it. I found a source for a pump rebuild kit and, though not cheap, ordered a head kit. Turns out they sent me an entire rebuild kit so I ended up rebuilding the lower unit as well (rings and bearings). I then found a decent 5 hp single phase motor on craigslist for real cheap and swapped it out for the 7.5 hp, making a drive pulley size reduction as well. I also had to purchase a magnetic starter for the compressor because the original owner either kept it or it never had one being 3 phase.

At one point I read a post stating that a ‘D’ ring would be a good way to lift a compressor using an engine hoist, so I added one.

Then I read in another one of the posts on this forum where someone suggested that somebody ought to paint flames on their air compressor tank, so that is what I did. This is my first flame job.

The specs. on this compressor are:
HP: 5
Max Pressure: 175 psi
Pump RPM: 550
Piston Displacement: 32.9
Tank Size: 80 gal

Before:

After:

I also have several other compressors because compressors are like potato chips, you can’t just have one!

Old compressor calved a week ago . Purchased tank for $25.00 New Rolair pump for $325.00 reused my Baldor motor as well as pressure switch , gauges blow off valve , etc.

I was able to find a video with the exact unit running with a gas motor. Pretty cool! I have pinged the owner to see if he can tell me more on the engine and the flywheel size.

Thanks for the feedback. Big help!

 

[torquednutzcustoms]

Been reading along time. This forum is awesome. Thank you all for the help I have got by reading. Thought I'd start by showing off my setup. I have a small business in my shop that I do in my spare time. My compressor is a Curtis 5hp 80 gallon. I love it. Seams to keep up great. My wife was using the blast cabinet,a buddy was using the pressure blaster and I was grinding one day and she kept up well. I have added 3 inline filters, a aftercooler with a 7" fan, and I used 4 of those small fans bolted to a frame I made to keep the head cool. It don't seam like the pump pulley cools well. I also get fresh air from a 6" filter outside. I have a drop right after the cooler with a water seperator right there and it always has water in it not much but some. I never get water at the tools or in the cabinet. Setup seams to work well. Once again thank you all for the help with projects.

 

[customcabinetpro]

Hey guys I'm a newbie to this forum, so I thought it was time for me to share my find.

I got an Old Quincy QR 25 # 325 ROC 10 that was at a consignment auction center. It looked pretty tough when I got it. It was covered in many years of oil. All I did was convert it to single phase, replace the rear seal, side cover gasket, intake filter element, new belts, magnetic starter, change the oil, and a new Baldor motor.

This thing purrs like a Cummins! (or a Duramax if you are a GM person like me)

Specs:
5 HP (184T frame 1725 RPM 1 1/8" shaft)
80 Gallon Vertical
815 RPM
17.4 CFM @ 175 PSI

I added an intake muffler that reduced the noise level by 10db.

I also added a 220 volt electronic tank drain that is tied into the load side of the contactor, so it can only purge when the compressor is running razther than around the clock.

I also plumbed my oil / water separator drain into the main tank drain so when the electronic drain purges the water in the separator goes with it.

I graduated from an old Campbell Hausfeld 5 HP (spcl) 60 gallon single stage to the Quincy. There is no comparison obviously. When I started woodworking, I thought that the CH 60 gallon would be fine, and it was, that is until I started using an air orbital sander rather than the cheap $65 electric sanders I had used prior to. That poor old CH was a work horse though. At last toward the end it developed a severe knock so a buddy of mine offered my $50 to take it off my hands so I could get a bigger unit.

Here is a link to see it running.

I Know this is cheating but it is a compressor. Cat G3516TA, 1340HP, natural gas engine. Ariel 4 throw compressor.

 

[fstbusa]

 

[ford67guy]

A lot of top of the line compressors here...

I just picked this one up. Traded some car parts for it. Guy needed my parts and I needed a bigger compressor. Nothing exciting, but better than the 33 gallon oil-less craftsman I was running. Cleaned her up... removed some surface rust, added a new drain valve, and painted with some left over primer and flat black paint.

 

[akdiesel]

Nice ac unit but are those 2" inlet and outlet water lines on your water heater?

 

[Dan in Pasadena]

I think ou're seeing the foam pipe insulation he has on his water lines.

67 Ford guy, Who makes the Black Max and what is it's CFM output?

I ask because it looks like my older Harbor Freight unit I picked up last spring on CL for $285. I'm sure yours is a better maker than HF but I'm wondering if HF changed who they bought theirs from?

 

[ford67guy]

Yep, those are foam insulation for my water heater.

Hey Dan - It's made by Sanborn and puts out 12.7 cfm at 40 psi. I think Sanborn was purchased by Coleman in the late 80's or early 90's. I've read a few threads on here stating that, but I'm sure someone else can chime in. The plate on the tank says it was made in 1988.

 

[Trey T]

Looked at about 50 pages of this thread and this is the best setup yet.

I hate the look of air compressor pump and motor in a garage unless the whole unit is enclosed in a closet, out of sight.

It's been a long wait but thanks to the sale of a piece of property, I got to splurge a little. Here's the new compressor. It's a Chicago Pneumatic 5hp, 80 gallon compressor. It's extremely quiet. It uses a Baldor-Reliance motor and a 220v German made "squirrel cage" blower to exhaust hot air out the top of the enclosure. Even without the sound enclosure, it's a quiet compressor. Way overkill for my home garage but a welcome replacement for the 15 year old oilless Craftsman compressor that was absurdly loud. It's connected to a Parker 3/4" filter/regulator combo and piping throughout the shop with a hose reel at the front. A trio of Norgren filters are on their way for the individual outlets. I switched everything to 3/8" Milton V fittings. Just got it up and running last night. I fabbed up a little cart with retractable casters and hockey pucks underneath to allow me to roll it out for service.

 

[boojum]

I got this one at an auction. 5HP. I fixed the unloader valve, replaced an o-ring, replaced the shut off valve, replaced the run capacitor, cleaned the check valve, and added a mag starter. Still needs a new pressure switch it seems to be stuck at a 50 PSI differential but it's up and running.

Which pump model number is your compressor? Looks like the same as mine (TV340). Mine is posted on the previous page (post #1494)

 

[boojum]

Mine is a 335TV.

 

[64Trvlr]

Mine is a 335TV.

Nice compressor, how big is your tank?

 

[boojum]

I assume it's 120 gal. When I was wating in line to pay the guy in front of me commented on the idiot that bought the big tank compressor with the too small of a head.

 

[46Nash]

I was given this old Kellogg-American compressor from an old photo lab for free. It had a 3 phase 1750 rpm motor on it which I replaced with a single phase 5HP 3400 rpm motor with a new pulley so I didnt overspeed the pump. It works great and is really quiet and smooth. Very happy with it.

 

[Jeff May]

Just wondering, those of you who mounted or placed their compressor in their attic. Have you had any issues with vibrations? Also, what, if any precautions did you take for the high temps in the attic in warmer seasons?
Thanks,
Jeff

 

[creativecars]

I don't have pics yet, but I just picked up a Kellogg-American 6hp, 80 gal compressor. Before I install it I would like to repaint and maybe add some new decals. Does anyone know where I can find a paint code or color to match. It is an industrial light green. I used to just paint shop stuff as I wanted, but more recently I like the restored look. Thanks in advance.

 

[46Nash]

Yeah I'm also interested, would like to restore mine too.

 

[Curtis_Peterson]

I guess you guys have not seen too many Atlas Copco's in the US, when you have so many good domestic ones to chose from?

The two stage is a 200psi from 1965, all original down to the hoses, except for the pressure gauge which I crashed some years ago. Anyone have an original matching numbers gauge lying around

The single stage 100psi in the background is from the start a 1947 Greiff, but I mounted a 1962 Atlas' compressor on it when the original DeVilbiss gave up some 15 years ago. Both works and sounds great, at least in my ears

PS. that home made after-cooler was a damn good idea! My two-stage's air is a *little* hot when I turn it up to 200+psi!

Living in minnesota, I see LOTS of atlas copcos, mostly industrial use screw, the price for the recip compressors is a bit higher and no "local" dealer I.e. home depot or lowes sell them. You have to go through the distributor to get ahold of one.

 

[Ben Buck]

creativecars & 46Nash , I took a bracket from my old Sandborn to a Sherwin-Williams paint store, the gal said she used worse to match paint. She was spot on, I don't know the name of the paint, someone said graphite. I rolled it on, and it looks great. Sorry about the hijack, just trying to help.

As previously mentioned, you can take a small part to a paint store and they can custom mix a match, it will have to be rolled or brushed on. A spray can match is available at many paint stores, but it's quite expensive, I think like $50\ 12 oz can.

I used a sample sprayed with the Atlas Touch up blue. The blue I used to paint a 3" line on my walls and cabinets to tie all the colors together. It matches great and was rather easy. I do have the color code to the match listed in my Shop thread below in my Sig, if anyone else wants it.

Thanks. It has worked out quite well so far and I don't miss the noise at all. Ironically though, because the old loud one came on all the time it never scared me. The new quiet one scares the **** out of me when it kicks on.
